Table 2a compares the energy delivery of steel vs bismuth shot to a 40-yard target with l-IN oz. duck loads. Bismuth delivers I 1 percent more energy to the target than steel. Another measurement of the superiority of bismuth shot is demonstrated in Table 2b, which compares the lethal effective- ness of steel vs bismuth. Lethal energy is the energy at impact less threshold energy, which is the energy lost in penetration of the bird' s feathers and skin. Energy-density, a measurment of a pellet's lethal prop- erties, is determined by dividing the lethal energy by the pellet's diameter squared. Again, it is clear that bismuth shot simply overpowers and outperforms steel in every characteristic which results in more birds bagged and less birds crippled and not recovered. The final comparison we look at in this exploration is the mtternin performance of bismuth vs steel in 12 laue 2-3/4 TSLE 2e: PATTERNING PEI;'IHCE OF gIsMu'rlt vl STEEL S'EMETS I , PELLgT 30" CIICLE LOAD COUNT 40 YD+ 60 YD. 1-114 oz. steel 14 139 196 lol 1-/s o=. xlh I, 11 212 11,t 1-1/1 o steel #2 1ft 112 71 1-/1 oz.

No. Target Hits 7.95 8.75 Total Energy-Density 1.11 1.584 ii inch shells. Table 2c shows that bismuth puts more pellets inside a 30 inch circle time after time at every load, pellet size and distance. Reports from the field support these statistics. Hunters from all over are praising bismuth shotshells. They also say the extra cost of bismuth is more than made up by expending fewer shells to get more birds. The positive performance of bismuth is bringing waterfowlers who had given up hunting back out into the field to once again enjoy this time-honored sport. Bismuth shot is still somewhat difficult to find in gun shops and department stores because it is new, but as more and more waterfowlers begin to discover its advantages, it will become easier to find and no doubt less expensive to purchase. How- ever, the cost of producing bismuth is still substantially higher than the production costs of lead or steel, so it will likely remain a higher priced shell to use. But who counts cost when the pleasure of hunting like the old days is back. Next week the Outdoor page will host the final article in the bismuth series. It will examine handioading bismuth shot and :st several sources for purchasing bismuth shotshelis and bulk ;hot.

Fluffing If you are camping overnight in a cold environment, your sleeping bag is your best friend. But remember, it doesn't heat ou hjt, Thickness is warmth. To keep your body heat inside the bag, insulation is your best bet. The more insulation (clothes, blankets, even newspaper) you have in the bag or wrapped around you, the wanner you will stay. It is not a good idea to sleep with your head inside the bag. Your breath contains a substantial amount of water and if you keep your head inside, this moisture can dampen the bag's insulation and destroy its heat-keeping ability. Wear a hat to keep your head warm. Don't put it inside your sleeping bag. Change clothes before getting into your bag. NEVER sleep in wet clothes. Even perspiration can give you a chill during the night. Eating a candy bar or an energy bar just before going to bed will increase your metabolism and make your body generate more heat to keep you warm. Empty your bladder before going to sleep. It could save you a middle of the night trip in the cold and getting warm again will be a major effort Don't try to dry wet clothing by bringing them inside your bag with you. The moisture will only travel from wet clothes to sleeping bag and destroy its insulating abilities. The moisture will also make you more susceptible to getting chilled. Put tomorrow morning's clothing under your sleeping bag. This trick will warm them up for the cold morning and provide additional insulation. You will thank yourself for this bit of advice when you have warm clothes to put on the next morning. creates the thickness and insulation that is important to keeping warllL The most important rule is to keep your sleeping gear dry. Maintain your metabolism. Keep your body warm so it can send heat to your extremities. If your feet are getting cold, put a hat on. Avoid sweating. Wear layered clothing so you can add or subtract as necessary. Keep your head covered when cold and uncover it as you begin to warm up. Remember, your head accounts for your greatest heat loss. Recommended clothing for a one night camping trip includes at least 2 +shirts (wool is best, flannel next), 2 pairs wool or synthetic pants (no cotton jeans which absorb moisture), fishnet or thermal underwear, waterproofed boots, 2 pair heavy socks (wool is best), 2 pair light socks (synthetic is best), a windbreaker (as part of heavier parka or jacket), a stocking cap (wool is best), mittens (not gloves), and extra shoes. It is always best to stay dry whencamping in the snow, but you can expect to get wet and should he prepared. Boots or shoes which are not waterproof will start letting your feet get wet and cold in less than 15 minutes in the snow, depending on the temperature. The colder it is, the longer your feet will stay dry. Low top shoes will not keep the snow out. But leg insulators can be made from plastic bags and duct tape. Do not cover the bottom of your shoes with plastic as this will cause you to lose traction and possibly take a nasty fall. These simple rules will allow you to have an enjoyable winter camping experience rather than a search and rescue disaster. being found in brush in coves. Trout fishing has also been good at Government Wash and Hemenway Harbor. LAKE MOHAVE. On Saturday boaters had excel- lent success for large striped bass in front of Cottonwoud / Cove. Casting A.C. plugs produced stripers that weighed 26, 22, 15 and eight pounds. On Sunday the fishing turned off in theCottonwood L MEAD' Boaters and shore anglers alike are finding good winter fishing for striped bass in the lake's Boulder Basin, according to the Nevada Division of Wild- life. One shore angler reported catching an 11 pound striper over the weekend at Government Wash. The fish was taken with a chrome Pencil Popper lure. In addition to the big fish, Government Wash's anglers are finding fair to good action for stripers ranging from three to five pounds. The action at Hemenway Harbor has been spotty for stripers. Good success is being found at the intake tower at night and at Saddle Cove near Lake Mead Marina. Largemouth bass fishing has been good with the fish area most angle. were unable to get a bite. Fishing has been below par sine that time. Reports from Willow Beach indicate the striped bass fishing may be getting back on track. Success for stripers has been improving following the recent trout plants. EAGLE VALLEY RFERVOIR - Ice is now about two inches thick and is unsafe for ice fishing. ECHO CANYON RESERVOIR- Unsafe ice condi- tions are now being found at the lake. Some open water is now found around the edge of the reservoir. SCHROEDER RESERVOIR- High runoff from the stream has flooded the hiking trail that leads to the lake, making for unsafe conditions. Anglers are urged to avoid the lake until conditions improve.
